Oh Boy! What a mess! You have parts from atleast 3 different types of systems and none of them want to play nice with each other. Let alone be on the same kart together. It sounds like the engine is ok and that is a good start. Going to need you to pull off the clutch on the engine. Then throw it into the nearest garbage can. We will start there. What size is the shaft? Then start looking on Amazon for 30series TAVII CVT systems and a Genuine Comet belt to fit it. Then pull off the drive wheel and remove the belt shieve mounted there. You can put that on a shelf it may come in handy for fixing a washing machine or something later in life. Do not buy anything yet! Until we see some pictures of the whole shaft, engine, whole kart, drive tire, what kind of axle. Measure across the front of shaft of engine for diameter. We can help you. With some more pictures and measurements.

Ok, now we’re getting somewhere. The clutch, the pulley and the belt are in no way gokart compatible. If you got a centrifugal belt type clutch, belts would only last a matter of minutes due to the heat. There is no way to salvage any of it. Sorry. So that means you get to start over. You could just go the cheap route and get #40 chain, #40 60 tooth sprocket for the drive wheel and a #40 10 tooth centrifugal clutch and call it good. But the problem with that is it will be driven off road at varying speeds. That means a short life. No good for what you need it to do. That is why I’m suggesting the 30series TAVII CVT system with a #40 10 tooth sprocket with a #40 chain and #40 60 tooth sprocket for the drive wheel. But need those pictures to confirm fitment.

A better question is if they are so good why were they used for only 1 or 2 years on one or 2 models? Answer, they did not last.
Like I said earlier running through tall grass over rough ground at slow speeds will wipe out a centrifugal clutch in short order from heat. Once the bell turns blue from heat it gets deformed and brittle at that point it is no longer safe to use. Your kart, your meat sack, you decide.

Correct, you would need to gear it for low speeds at as high rpm as possible to keep the clutch engaged. But please convert to chain drive atleast.

You missed the point entirely.
Centrifugal clutches are for: tracks, racing, and long rides of constant rpm/load
CVT [Tav2, Comet30, Comet40] is for: Offroad, traffic type conditions involving Stop and go or inconsistent speeds and torque demands
Comet30 fits most 3/4" shaft engines
Comet 40 fits most 1" shaft engines
CVT= Constant Variable Transmission meaning its a Centrifugal clutch (driver pulley) and Transmission "gearbox" (driven pulley) attached by a belt, in one fairly compact unit

I think he is more concerned about it being cheap than working properly. I love when people come askin for help then won’t take it when it is given to them. Oh well, some have to learn the hard way.
